Thermal and electrical conductivity of single crystalline kesterite Cu2ZnSnS4

For single crystalline sulfur-based kesterite Cu _2 ZnSnS _4 the electrical and thermal conductivity are measured from 20 K to 320 K. The electrical conductivity decreases exponentially with decreasing temperature. The temperature dependence can be assigned to Mott-variable-range-hopping, an electri...
